MapiCalendarTimeZone timeZone = new MapiCalendarTimeZone(TimeZoneInfo.Local);

Setting Reminder with the Created Appointment

A reminder can be added when an appointment is created. These alarms can trigger based on different criteria like n minutes before the schedule starts, repeat n times at n intervals. Different tags can be used to create these triggers in the script enclosed by BEGIN:VALARM and END:VALARM within an appointment. There is a number of variants in which the reminder can be set on an appointment.

Setting a Reminder by Adding Tags

The following code snippet shows you how to set a reminder by adding tags.

// For complete examples and data files, please go to https://github.com/aspose-email/Aspose.Email-for-.NET
// The path to the File directory.
string dataDir = RunExamples.GetDataDir_Outlook();

string location = "Meeting Location: Room 5";
DateTime startDate = new DateTime(1997, 3, 18, 18, 30, 00),
endDate = new DateTime(1997, 3, 18, 19, 30, 00);
MailAddress organizer = new MailAddress("[e-mail]", "Organizer");
MailAddressCollection attendees = new MailAddressCollection();
attendees.Add(new MailAddress("[e-mail]", "First attendee"));

Appointment target = new Appointment(location, startDate, endDate, organizer, attendees);

// Audio alarm that will sound at a precise time and
// Repeat 4 more times at 15 minute intervals:
AppointmentReminder audioReminder = new AppointmentReminder();
audioReminder.Trigger = new ReminderTrigger(new DateTime(1997, 3, 17, 13, 30, 0, DateTimeKind.Utc));
audioReminder.Repeat = 4;
audioReminder.Duration = new ReminderDuration(new TimeSpan(0, 15, 0));
audioReminder.Action = ReminderAction.Audio;
ReminderAttachment attach = new ReminderAttachment(new Uri("ftp://Host.com/pub/sounds/bell-01.aud"));
audioReminder.Attachments.Add(attach);
target.Reminders.Add(audioReminder);


// Display alarm that will trigger 30 minutes before the
// Scheduled start of the event it is
// Associated with and will repeat 2 more times at 15 minute intervals:
AppointmentReminder displayReminder = new AppointmentReminder();
ReminderDuration dur = new ReminderDuration(new TimeSpan(0, -30, 0));
displayReminder.Trigger = new ReminderTrigger(dur, ReminderRelated.Start);
displayReminder.Repeat = 2;
displayReminder.Duration = new ReminderDuration(new TimeSpan(0, 15, 0));
displayReminder.Action = ReminderAction.Display;
displayReminder.Description = "Breakfast meeting with executive team at 8:30 AM EST";
target.Reminders.Add(displayReminder);

// Email alarm that will trigger 2 days before the
// Scheduled due date/time. It does not
// Repeat. The email has a subject, body and attachment link.
AppointmentReminder emailReminder = new AppointmentReminder();
ReminderDuration dur1 = new ReminderDuration(new TimeSpan(-2, 0, 0, 0));
emailReminder.Trigger = new ReminderTrigger(dur1, ReminderRelated.Start);
ReminderAttendee attendee = new ReminderAttendee("[e-mail]");
emailReminder.Attendees.Add(attendee);
emailReminder.Action = ReminderAction.Email;
emailReminder.Summary = "REMINDER: SEND AGENDA FOR WEEKLY STAFF MEETING";
emailReminder.Description = @"A draft agenda needs to be sent out to the attendees to the weekly managers meeting (MGR-LIST). Attached is a pointer the document template for the agenda file.";
ReminderAttachment attach1 = new ReminderAttachment(new Uri("http://Host.com/templates/agenda.doc"));
emailReminder.Attachments.Add(attach1);
target.Reminders.Add(emailReminder);

// Procedural alarm that will trigger at a precise date/time
// And will repeat 23 more times at one hour intervals. The alarm will
// Invoke a procedure file.
AppointmentReminder procReminder = new AppointmentReminder();
procReminder.Trigger = new ReminderTrigger(new DateTime(1998, 1, 1, 5, 0, 0, DateTimeKind.Utc));
procReminder.Repeat = 23;
procReminder.Duration = new ReminderDuration(new TimeSpan(1, 0, 0));
procReminder.Action = ReminderAction.Procedure;
ReminderAttachment attach2 = new ReminderAttachment(new Uri("ftp://Host.com/novo-procs/felizano.exe"));
procReminder.Attachments.Add(attach2);
target.Reminders.Add(procReminder);
target.Save(dataDir + "savedFile_out.ics");

Convert Appointment EML to MSG with HTML Body

Since version 19.3, Aspose.Email provides the ability to convert Appointment EML to MSG while retaining the HTML body of the appointment. Aspose.Email provides a MapiConversionOptions.ForcedRtfBodyForAppointment property which has a default value of true. When the value of MapiConversionOptions.ForcedRtfBodyForAppointment is set to true, the appointment body is converted to RTF format. To keep the appointment body format in HTML format, set the value of MapiConversionOptions.ForcedRtfBodyForAppointment to false.

The following example demonstrates the use of MapiConversionOptions.ForcedRtfBodyForAppointment property to keep the appointment body format in HTML format.

// For complete examples and data files, please go to https://github.com/aspose-email/Aspose.Email-for-.NET
// Outlook directory
string dataDir = RunExamples.GetDataDir_Outlook();

MailMessage mailMessage = MailMessage.Load(dataDir + "TestAppointment.eml");

MapiConversionOptions conversionOptions = new MapiConversionOptions();
conversionOptions.Format = OutlookMessageFormat.Unicode;

// default value for ForcedRtfBodyForAppointment is true
conversionOptions.ForcedRtfBodyForAppointment = false;

MapiMessage mapiMessage = MapiMessage.FromMailMessage(mailMessage, conversionOptions);

Console.WriteLine("Body Type: " + mapiMessage.BodyType);

mapiMessage.Save(dataDir + "TestAppointment_out.msg");
